Question

look at he image above that illustrates the basic structure and function of an enzyme. we call this model a lock - and - key, since the enzyme has a specific shape that allows it to fit a particular substrate. what do you think would happen if the enzyme that helps break down sucrose became damaged so that its shape was changed (denatured)?

Explanation:

Enzymes work based on their specific shape in the lock - and - key model. A damaged (denatured) enzyme loses its proper shape. This means it can no longer bind specifically to its substrate (sucrose in this case). Without proper binding, the enzyme - catalyzed reaction (breakdown of sucrose) cannot occur efficiently or may not occur at all.

Answer:

The breakdown of sucrose would be impaired or stop because the damaged enzyme could no longer bind to sucrose effectively due to its changed shape.
